Welds are aesthetically pleasing and smooth in transition under working mode of continuous laser. With little deformation and tiny bulge, slight or almost no further polishing is needed, saving labor and time costs. Welding strength of some metals is even higher than parent metal. The tensile strength is generally high.

The electro-optical conversion rate is as high as above 45%, which is 15 times that of solid YAG laser (3%), and its power stability is ±0.5%. Pumping source can last for over 100000h, basically maintenance-free. Welding wire is needless without extra cost for consumables.

Laser welding usually gives rise to less smoke dust, low noise and almost no pollution. Compared with traditional welding patterns, the laser welding is regarded as the first choice for users who are anxious to work in a clean environment.
